Changing the bulb 

 

You must not attempt to change the bulb immediately after the microscope has been 
used, as the bulb will still be hot and so there is a risk that the user could be burnt. 
Before changing the bulb the device must be switched off and unplugged. 
 
To  change  the  bulb,  tip  the  device  carefully  to  the  back  or  side.  When  doing  this, 
please make sure that all microscope components are firmly fixed. The bulb holder is 
on the underside of the device. It can be opened by undoing the screws on the holder 

(see illustration)

. We recommend that here you should also test again, to check that 

heat is no longer being produced. The defective bulb can be pulled out of the socket 
and  be  replaced  with  a  new  one.  After  the  bulb  holder  has  been  replaced  in  the 
underside of the device and the screws replaced, the bulb replacement procedure is 
complete. 
 
Important: 
When fitting the new bulb into the socket, it must only be handled with sterile gloves 
or using the bulb packaging film. Grease and dust residue can have a negative effect 
on the light quality and service life.
